ances, and is particularly concerned with the,

construction ofa tool, which is'adapted to be simultaneously moved" andoscillated 1 too along the surface to be grained.

In grain-ing flat surfaces, particularly floors, it frequently occursthat the boards are uneven, and in consequence thereof, the

surfaces to be grained are not in thesameplane. Under such conditions itis 'difiicult to secure satisfactory results by employing a grainingtool; which-comprises a rigid structure. i

An object of my invention is the pro-- visionof a graining tool whichmay be em-' ployed for graining'uneven surfaces, and for producingsatisfactory results thereon,y-the' result being accomplished bymakingthe body of the tool somewh-atfiexible or articulated, while atthe same time, "it is stiff enough to prevent undue distortion of thegrainingsurface on the tool.- Another object is the provision of atool'having rel ati-vely' movable sections, whichare arranged to bemoved selectively the operator dur ing the graining operation. r

In accomplishing the above objects, Ipro vide a tool having a headcomp-rising a series of'sections which are movable relatively to eachother and which are arranged to receive a suitable graining pad.FurthermoreI provide means forsecuring these sectlons 1n alignment witheach other, and for.

allowing them to be selectively moved, while the tool, as a unit, isbeing drawn along the surface to be grained;

The means for accomplishing the, above objects will be more fully setforth in the following description which relates to the drawing, and theessential characteristics of my invention will be set forth in theclaims.

'M'y invention, in general, contemplates the cprovision of a grainingitool which en ables various portions of a graining' pad to bepressed-selectively-into engagement with the surface to be grained; Thetool preferablyhas a segmental body tOaWlllCh is secured a graining pad10 in the form of a ribbed" sheet'of rubber or: similar materialpositioned upon the arcuate bottom o-f the- The tool body comprises apluralityof sections 11, which are shown as three in number, and as'POSitIOD'GdadJaCBIIt each other-so; as tob'egcapable of' -being-" moveda" slight amountvertically and relatively to each other.- Each of thesections is preferably a block of wood'havi-ng recesses 12 on the uppersurface thereof, for receivingthe first, second and third fingersrespectively, of' the operator. The-blocks 11 are shownas securedtogether at the top-by means of flexible'plate, member or portion 13,which may be a strip -o'fjleather extending across the rope-feachsectionandrigidly secured thereto 1 That portionof the plate directlyabove the 're'cessesl2, may be 'cut away-tov permit the fingers" to" beinserted thereselectively exerted 'upon eachblo'ck. I The flexible'rain-in-g surface 10, together with the fiexi bleqstrip 13,.servesi toretain the sections togetherand atthesame time to permit each section tobe moved relatively to an adjacent section with-comparative case: It isobvious, however, thatthe vari ous sections may be held togetherby othermeans? for" instance, "the articulated "body may be made by taking asolid block and cutting part way therethrough so asto leave a narrowconnecting strip between the adjacent sections, as shown in Fig. .4.This and other equivalent constructions are all included within myinvention. The pre- The movement of the'hand, during the I grainingoperation is similar to the movement customarily utilized with the rigidform of block. Where portions of the surface to be grained are hollowedor uneven, then the operator may press more firmly upon that sectionimmediately over the low spot, and thereby effect an even grain withoutstopping the forward motion of the tool.

From the foregoing description, it will be seen that I have provided agraining tool, which is quite simple in construction, and which iscapable of being employed for satisfactorily graining uneven surfaces.Furthermore it will be seen that I have provided a tool which permitsvarious portions of the tool to be selectively depressed by theoperator, during the graining operation, without interfering with themovement customarily employed for such process.

Having thus described my invention, I claim:

1. In'a graining tool, the combination of an articulated body and agraining pad carried thereby.

2. In a graining tool, the combination with a graining pad, of aplurality-of sections positioned .adjacent each other, and means soconnecting the sections that they may beindividually moved relatively toeach other.

3. In a graining tool, the combination with the graining pad, of asupporting head therefor, said head comprising sections positioned adjacent-each other and movable relatively to each other.

4. In a graining tool, the combination with a flexible graining surface,of a supporting head therefor, said head comprising sections positionedadjacent each other and movable relatively to each other, and meanswhereby each section may-be moved relatively to another section, bypressure exerted thereon by a finger of the operator.

5. In a graining tool, the combination with aa flexible grainingsurface, of a supporting body therefor, said body comprising segmentalsections positioned end to end, and means for connecting the sections sothat they are movable relatively to each other.

6. In a graining tool, the combination with. a plurality of sectionspositioned side by side, a graining pad positioned on the bottom of saidsections, and a flexible member positioned adjacent the top of saidsections, whereby each section may be moved relatively to an adjacentsection.

7 In a grainnig tool, the combination with a plurality of segmentalsections positioned end to end, a ribbed rubber graining pad extendingacross the bottom of the sev eral sections, and a flexible membersecured onthe top of the several sections, whereby each section may bemoved relatively to the adjacent section.

8. In a graining tool, the combination with a graining surface, of asegmental body carrying the same and having individual finger recessesin its top surface.

9. In a graining tool, the combination with a graining surface, of aseries of supporting sections having recesses therein,each of saidrecesses being adapted to receive a finger of the operator, andmeanswhereby each section may be moved relatively to and independentlyof an adjacent section.

10. In a graining tool, the combination with a graining pad, of a seriesof supporting sections therefor, and flexible means associated with saidsections for permitting them to be moved relatively to each other.

11. In a graining tool, the combination with a graining surface, ofthree supporting sections therefor, each of said sections having arecess therein and arranged to receive the first, second and thirdfingersrespectively of the operator.

12. In a graining tool, the combination with a flexible grainingsurface, of aseries of sections positioned thereabove, each of saidsections having recesses extending downwardly from the top thereof, aflexible member positioned across the top of said sections and providedwith aperturesin registration with said recesses, and means whereby eachof said stctions may be moved relatively to an adjacent section by afinger of the operator pressing downwardly.

In testimony whereof, I hereunto aflix my signature.
